In a medium roasting pan (9"x13") or a 12" oven safe skillet, combine the first five ingredients. Whisk the wine, balsamic, and olive oil together, drizzle over the vegetables and toss to combine. Season with salt and pepper.

Place the pan on the middle rack in the oven, uncovered, and allow the vegetables to cook slowly, stirring only a few times during the process, being careful not to break the tomatoes. Slow roast for 4 – 4 1/2 hours.

The resulting confit, or tomato "jam" can be used to dress pasta, slather on crusty bread, or as an accompaniment to slow roasted meats or poultry.
